摘要： 对皖西大别山区2种森林植被类型土壤呼吸速率进行统计分析,结果表明,不同季节2种植被类型土壤呼吸速率随时间呈先升后降的变化趋势;土壤呼吸速率与地下5 cm、10 cm的土壤温度有较好的相关性;杉木林土壤呼吸速率与5~10 cm土层有机质含量呈极显著相关,相关系数为0.978(p<0.01);麻栎林土壤呼吸速率与0~5 cm土层有机质含量呈显著相关,相关系数为0.928(p<0.05)。

关键词: 亚热带森林, 土壤呼吸速率, 土壤温度, 土壤有机质

Abstract: The soil respiration rate of two forest types in Dabieshan Mountain in the western of Anhui Province was statistically analyzed.The results showed that the soil respiration rate of two forest types increased first and then decreased in different seasons.There existed great correlation between soil respiration rate and soil temperature at the depth of 5 cm and 10 cm.There was also highly significant correlation between soil respiration rate and soil organic matter content at the depth of 5~10 cm layer in Chinese-fir forest with the correlation coefficient was 0.978 (p<0.01).In bast oak forest, the soil respiration rate was significantly correlated with soil organic matter content in 0~5 cm layer (0.928, p<0.05).

Key words: subtropical forest, soil respiration rate, soil temperature, soil organic matter
